Each level is scored on its own scale — elementary, middle, and high are never ranked against each other.
The elementary years
The elementary schools average 49.5/100 — 10.7 points above the state average, with 2 of 5 in the Strong band.
5 elementary schools span 27 points around an average of 49.5.
Mayflower Elementary (65/100) holds the Strong band — 38.5% of its students exceed the state standard, against a level average of 27.2%. 3 schools here rank as Growth Engines — returning cohorts gaining more than most schools statewide.
27 points separate the top and bottom elementary schools — the district average won't predict the school in front of you.
The middle years
One school defines the top: Clifton Middle sits 19 points clear of the field — the other 1 middle schools are a different conversation.
2 middle schools span 19 points around an average of 43.5.
Clifton Middle (53/100) holds the Strong band — 28.6% of its students exceed the state standard, against a level average of 24.0%.
The suspension rate averages 7.2% against 3.6% statewide — worth a direct question on a visit.
The high school years
One school defines the top: Monrovia High sits 29 points clear of the field — the other 2 high schools are a different conversation.
38 points separate the strongest and weakest of these 3 high schools — the average hides more than it tells.
1 continuation/alternative school not plotted — it ranks within its own class, not on this statewide axis.
Monrovia High (65/100) holds the Strong band — 24.8% of its students exceed the state standard, against a level average of 12.4%.
33.7% of students are chronically absent (state: 23.1%) — chronic means missing 10% or more of the school year. Whatever the scores say, ask each school what it is doing about attendance.
What it means for your family
Compare schools at your child’s level before deciding on an address. The strongest attendance-zone candidate is Mayflower Elementary at 65/100 — confirm the exact boundary with the district before the house.
1 runs a magnet program — enrollment paths that don't depend on your address. If your zoned school sits low in the appendix below, those lotteries and applications are the levers worth the paperwork.
A band is a position, not a prophecy — 5 campuses here rank as Growth Engine (3) or On the Rise (2), their returning cohorts gaining more than most schools statewide. Ask your school two questions: what happens for a kid who arrives behind, and what the classroom looks like for one who arrives ahead.
